Individual Assignments (2)

• Write an application that interfaces a user with an input and/or output device that you made.

We have not yet been able to access the FabLab, nor the corresponding equipment to carry out the physical practices, which in my case are very necessary since it is not the same as simulating situations with characteristics given by default.

As I have confessed before, these new disciplines are not my strength and to top it off I had not even heard them before, therefore, I am still trying to understand many things and this situation has not been easy for me.

From the class with Neil, I heard that Processing is one of the softwares that contains a language and a comfortable environment to work with, so here we go... With the local instructor we had a class in which we were shown a project already completed that we could follow, However, there is nothing in this world that serves us better than to do and try with a step-by-step guide.

In this case and trying to save time, I have been guided by a tutorial, combining the ultrasonic sensor used in week 9 and adding a servo motor that I just received (16-5-20) and that will be great resources if I can try its function from now on for my final project; I will do it using Arduino Uno as a platform to simulate the connections of the components with the own pcb due to the lack of access to the FabLab and to be able to manufacture the pcb that I have designed in previous weeks.

Here is the Arduino code, using the Ultrasonic Sensor and the Servo Motor, and then the Processing code is created and edited, for connectivity we use the Arduino Serial Monitor, connected to communication port 5, which function as a link for generate the respective visualization and the final result.

I had to do a good practice of trial and error to begin to understand the operation of the two applications and especially because I was guided by a video tutorial where his writing changed a little with what I was getting used to, just to have a little of experience with something new. The guide code came with some errors, but it can be solved with the help of the same software. After this I started to fiddle with the language to adapt it to what I think I need.

To continue this assignment, I have the parts list to use and move my assignments forward until I can build my pcb:

• 1 x Arduino Uno.
• 1 x Ultrasonic Sensor HC-SR04.
• 1 x MG 995 Servo Motor.
• 2 x 1x4 wires.
• 3 x 1 wires.
• 1 x Double contact tape.
• 1 x Plastic strap.

The ultimate goal of this assignment is to design and program an output device, in our case a servo motor and I will add an ultrasonic sensor to it because I am preparing for my final project where the sensor can make the servo move.

In this case take an example shown on the web and first try to understand the connection of components, part of the arduino code already had it from previous weeks of playing with the ultrasonic sensor and the servo motr separately; In this case I saw some video tutorials to understand how to work from Arduino to Processing.
